While you sleep your body enters into repair mode: the brain recharges, important hormones are released, and cellular rejuvenation takes place. When it comes to our skin, blood flow increases, along with DNA repair, cell proliferation (cell turnover), temperature, barrier permeability, penetration, itching, and moisture loss, in addition to decreased barrier recovery. This makes our skin even more receptive to the absorption of the types of active ingredients found in skin treatment solutions, and is therefore the best time to nourish and cure our skin. A gel cream formula is especially effective as the skin experiences more trans-epidermal water loss at night. This consistency helps to replenish crucial hydration, complementing the body's natural fluctuations.
